I know what airgaped means, but I thought my coldcard already meets these criteria
Yes, a ColdCard is an airgapped hardware wallet.
The issue with the coldcard and paper wallets is, that you need to save them on a Micro SD card and open them on a Computer to be able to view them. This will always compromise the wallets if you dont use a special computer for it. Almost seems like they dont want you to use that feature.
I haven't really thought about it. I mean if the computer is connected to the internet, or it uses a problematic OS, then there will be a problem no matter what type of wallet you choose to use.
